It is.  Summarising the flow:

    bool outputsize_given = false;
    int outputsize;

    switch {
    case ...:
        outputsize_given = true;
        if (...)
            outputsize = INT_MAX;
        else if (...)
            outputsize = sc_width();
        else
            outputsize = atoi(cp);
    }

    if (!outputsize_given) {
        outputsize = ...;
    }

And from then on they're all reads.

Again, no warning from cc here.
